Acceptance Testing
Acceptance Testing is the final stage of testing where the software is tested against its acceptance criteria, ensuring it meets all specified requirements and is ready for delivery to the end-user or client. As part of Regression Testing, Acceptance Testing verifies that modifications or enhancements made during development have not negatively impacted existing functionality while confirming the software's overall suitability for the intended purpose. By validating the software against acceptance criteria, this process provides confidence in the software's ability to perform as expected and satisfy user needs within the broader context of Software Testing and Software.
